Ee it known that I, SIERRA LEONE RICH* riens, a. citizen of the United States, residing at Baltimore, in the State of li/aiyland7 have invented certain new and useful improve ments in Combined Broilers and Ovens; and I do declare the following to be a i'ull,' clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to niake and use the saine. y

lfhis invention relates to injiproveinents in gas ovens, and more particularly to an oven in which is mounted a duplex facing system `of jet barriers between which burnis suspended a broiler rack adapted to inclose the article to be broiled.

rlfhe object of the invention is to provide an oven of this character' which may be readily converted from a baiting to a broiling oven and. vice versa. I

With these and other objects in view7 the invention consists of certain novel features of construction, combination' and arrangement or" parte as will, he more fully described and claimed.

ln the accompanying drawings :fFigurc l represents a front elevation of a gas range equipped with this improved oven. Fig. l represents a longitudinal vertical section thereofwith the oven arranged for baking. Fig. 3 is a similar view with the oven arranged for boiling. Fig. l is a transverse section taken on the .line -r l of .5 is horizontal section taken e 5 5 of V improvement is shown applied to a ove or range having what is known as 'n elevated oven i., the walls oit which are the usual double construction having aslestos or other insulating material between ein. The usual horizontally arranged s a arc employed such as are ordiused in baking ovens and supi gas to which is controlled by the usual llithin this oven l upright jet burner tones L3 and el` are located, one at each end or the oven. t ic other .movable to vary the space between tnen'i and position the burner or llame plates and S thereof a suitable distance from the. zuticle to be loi-oiled.

righe, inner face of one end wall of the oven l co dstitutes the back plate of the fixed burner boi; 3, and 7 thefront plate thereof One oithese boxes is fixed and which latter has an angle iiangeubraclet 8 which otfsets said front burner plate 7 from the bach plate or oven wall 3 sumciently to constitute a gas supply chamber 9, between said plates which supplies the series of burner jets 5 formed in the front plate 'i'. rihis front plate 7 is provided on its outer face with a plurality of vertically spaced shelf racks or brackets l0 which are designed to cooperate with similar brackets l0 on the movable burner box le for supporting shelves or other articles as may loe desired. A gas pipe 11 supplies gas to the fixed burner `boa 3 and the passage oi gas therethrough is controlledk by a suitable cock.

T he movable burner box e is provided at its opposite ends with casters or rollers l2 which travel on the inner faces of the upper and lower walls of the oven l to facilitate the adjustment oi said box toward or away from the fixed burner 3.

The movable burner boi.; is preferably constructed as shown clearly in Figs. 2 and 3, being composed o' spaced walls 13 and lli connected "their opposite ends to form a partition which extends approximately the full. height oi the oven and on which the rollers i2 kare mounted. This partition forms the bacia plate or wall of the burner bolty il. the iront plate il ol' which is offset. i'roni said back wall by an angle flange 16 a distance suilicient to provide a gas clianisarei-'ieee lvm. fi, ieisl ber l? freni which gas supplied to the openings i8 in the lront p ate thereof. 'On the outer oit this ont plate sh l* br iets itl are scoured and disposed 121 ali-. nient with the brackets 1Q on the fixed burner box. 'lhcse brackets support the shclv'es, not shown, when the oven is used for baking and when used a broiler 'they support an upright broiler to be described. yThe gas chamber l? has a coupling -19 at its lower end into which a gas pipe 20 is clesigV 'to project when said movable box is inoved toward the .fixed box a certain distance as shown in Fig. 3, and this pipe 20 si epilee gas to the chamber 17 and 'is conti i l by a suitable cock 2l.

The movable partition to which ,the is attached has recesses 23 in burner box its lower end 'for the passage therethrough of the burner pipes or tubes :2, as shown clearly in Fig. e, said burners extending approximately' the full length of the oven to lll@ supply suitable heat thereto when the oven is used for baking, suiicient space being left at the end of said burners for the movable partition and burner box It when in inoperative position as is shown clearly iii Fig. 2. A jointed handle 24 is secured to the rear face oi the movable partition by a suitable coupling. l`lie sections of this handle are provided with lugs 25 and 26 for a purpose to be described. This handle passes loosely through an opening in one end oi' the oven, said opening being sutciently large to permit the lugs 25 and 26 t0 pass therethrough when the handle is moved upwardly, said handle resting on the lower wall of said opening when in normal position.

A suitable pilot 2T is disposedin position to light the burners of the oven when used for either baking or broiling purposes and it may be of any ordinary or desired construction. .See Figs. 34 and. 5.

An upright broiler :2S is designed to be supported between the burner boxes 3 andv Il on the shelf brackets of said burners as shown clearly in Fig. 3. This broiler is composed of hingedly connected sections 29 lit) and 30 composed of suitable oraminous material, preei'ably woven wire such as is ordinarily employed in constructing broilers. llates 3l and 32 are iixed to the upper free edges ot' these sectionsl 2S) and 30 and extend outwardly in opposite directions in planes at right angles to the sections and are of a width suiiieient to space the sides ot' the broiler a suitable distance iroin the liame or iront plates of the burner boxes 3 and 4, said plates being adapted to rest on the shelf brackets of said burner boxes. llaiidles 33 extend laterally i'roiii one end of said sections aiid arc adapted to be connected by a sliding ringI 34 which may be adjusted to bring said sections toward each other or to space them farther apart as may be desired, according to the thickness of the meat or other article to be claiiipcd between them.

A drip pan 23.3 is supported below said broiler on the shelf brackets as is shown in liig. 3 and is adapted to catch the drippiiigs lroiii the article being broiled. When it is desired to use this oven for baking the niovable partition witli the lire box t attached thereto is drawn toward the end of the oven having the aperture therein, through which the handle 2t slides, the movement of the partition being accomplished by grasping the handle and drawing it outwardly into the position shown in Fig. 2, and when it is released the outer hinged section thereof will l'old downwardly and the lug 26 en the linner section will engage the outer face of the end wall of the oren and lock the partitioh in withdrawn position untii it is again desired for use. Wlien this movable partition and re boa: tt are in the position above described and shown in Fig. 2, the oven is ready for use as a baker and the shelves (not shown) maybe supported on the brackets 10 and 10 secured to theburner boxes, the burners 2 being supplied with gas and lighted for furnishing the heat necessary for the baking operation, the as which supplies the burner boxes having een first cut ol'. When in this position the partition carrying the movable burner box 4 is locked against inward movement by the engageiiient of the lug 25 with the outer face of the end wall of the oven.

When it is desired to use the oven for broiling, the handle 24 is straightened out into the position shown in Fig. 3, and pushed inward to its extreme inward limit which is controlled by the length of the pipe 20 which projects into the coupling at the lower end of the burner box 4 as shown in Fig. 3 and prevents further movement of said partition in this direction. The cock controlling the supply of gas to said pipe may then be turned to permit the gas to enter the chamber of the burner box 4 and permit it to pass out through the jet openn in s algo turned into the chamber of the xed burner box 3 and ignited when it issues through the 'ets formed in the front wall 1S, where it is'ignited. The gas is thereof, there y supplyin Haine on opposite y sides of tlie broiler 28 w iieli has been suspended from shelf brackets on said b ner boxes. When in this position the partition carrying the movable burner box 4 is locked against rearward movement by the engagement of the lug 26 with the inner face of the end wall of the oven. See Fig. 3.

From the above description it will be obvious that the oven l may be quickly conrei-ted either into an oven for baking or into a broiling oven, as may be desired.

While I have described my invention with more or, less iniiiuteness as regards details v and as being embodied in certain precise forms, vI do not desire to be limited thereto unduly any more than is pointed out in the claims. 0n the contrary, I contemplate all proper changes in form, construction, and arrangement, the omission of immaterial elements and substitution of equivalents as cir cuinst-ances may suggest or render expedient I claim as my invention l. A gas oven having an upright xed burner therein, an upright burner freely movable toward and away from said fixed burner, a'. handle secured to the rear wall of said movable burner und provided with a. pivoted outer section having longitudinally spaced lugs, said oven having an o ening in one end wall through which said iandle is adapted to slide freely, said opening being of greater diameter than the handle to er` mit the lugs thereon to pass therethroug 2.
